the word 'widen' is a transparent english formation built from native germanic elements. its core, 'wide', descends from the proto-germanic wīdaz, which itself likely derives from the proto-indo-european root wi- ("apart, asunder"), conveying a sense of separation and thus, broad extent. the suffix '-en' is a productive verb-forming element in english, originating from the old english '-nian', used to create verbs from adjectives, as seen in 'deepen', 'sharpen', and 'cheapen'. the literal construction "to make wide" perfectly captures the word's modern meanings, which range from the physical act of broadening something to the more abstract process of increasing scope or degree.

Structure: wide (adjective) + en (verb-forming suffix) - wide: from old english wīd ("wide, vast, spacious"). functions as the adjectival root describing extent. - en: from old english -nian, a verb-forming suffix. functions to convert an adjective into a verb meaning "to make or become (adjective)".
